Toshiba may be onto something truly amazing here, where they've developed the world's first eco-friendly multifunction printer that is capable of erasing text and images on printed documents. This is a great feature as it would allow for paper to be reused.

The Toshiba e-STUDIO 306LP/RD30 printer sports a special toner that produces an erasable colour, which is removed from paper when passed through at a high enough temperature. This means the paper can be reused time and time again, instead of being thrown away or discarded when it's not needed anymore. A single page recycled five times would provide a 57% reduction in CO2 emissions for the entire printer system - this isn't counting the savings consumers and businesses would have on paper costs, too.

The printer itself is also a step forward in the green world, being made from bio-based plastics instead of the traditional petroleum-based plastics. Toshiba's e-STUDIO 306LP/RD30 launches in February 2013 starting in Japan, and it'll jump across the pond later in the year.
